    Soda Ash is a white, granular powder primarily used to condition and soften make-up water and raise pH.


    Treat out hardness due to calcium in make-up water. Raise pH.


    Eliminate calcium ions by removing them as insoluble calcium carbonate. Maximize the performance of bentonite and polymer product.

    Recommended Treatment

    lbs./bbl* lbs./100 gals kg/ m³
    0.2 – 0.85 0.5 – 2.0 0.6 – 2.4
    * 1 bbl = 42 U.S. gallons
    • Hardness (below 120PPM) and pH levels of make-up water should be checked prior to addition of Soda Ash
    • Addition of Soda Ash should always be done prior to addition of bentonite or polymer to the fluid system
    • Soda Ash should not be added at the same time as other drilling fluid components
    • When treating make-up water pH ranges should be maintained between 8.5 – 9.5

    The above are generalized concentrations of Soda Ash sodium carbonate to be added to fresh or salt water-based drilling fluids. The ultimate usage concentration will be based on local geology, water chemistry, application and mixing efficiency.
